Answer 2

Answer-

✔ CO (Carbon Monoxide) does not cause acid rain.

⭐ Acid rain is the rain with high level of hydrogen ions. It has low pH. Normal clear rain has pH between 5.0 to 5.5 but typical acid rain has pH 4.0 . The main gases responsible for acid rain are: Carbon dioxide, SO2 and Nitrogen Oxides. Carbon Monoxide do not play a single role in acid rain.
